This repo will contain some projects that I've faced during learning Embedded Linux.

If you have a problem with HDMI in RPI-4 :
-
config.txt content :
max_framebuffers=2 force_hotplug=1 hdmi_force_hotplug:0=1 #hdmi_safe=1 config_hdmi_boost=4 hdmi_group:0=1 hdmi_mode:0=4 #arm_64bit=0 boot_delay=1
-
cmdline.txt content : video=HDMI-A-1:1024x768@60D

I had a problem for not booting and stucking at image of raspberry
- Add to config.tst kernel=yourImage.img
-
Problem : end kernel panic not syncing attempted to kill init raspberry It happened because the kernel tries to run systemd code. running file /sbin/init show us a 64 bit executable. so kernel tries to run 64-bit on 32-bit image.
- The solution is to delete /sbin/init
-
problem : Entering in initramfs : solution : fix the rootfs in your cmdline.txt
-
problem : not detecting wlan0 ? solution : add arm_64bit=0 solution 2 : add the right modules for the right (uname -r)
